Pilot Release: Custom Fields in Crossware Me

We have released the pilot version of Custom Fields, giving organisations the ability to let end users update selected field values directly through Crossware Me.

Administrators can choose which fields are available for editing, helping organisations keep user profile information accurate while maintaining control over which values can be updated.

This feature is currently being rolled out to a limited number of customer tenants as part of our pilot release.

To participate in the pilot, please contact the Crossware Support team.

Important notes:

  • When both server-side and client-side signatures are assigned, the signature panel will continue to display both, maintaining existing behaviour.

    • No default signature has been selected in the signature panel.

  • When the Select feature is disabled, the signature panel will only display server-side signatures.

  • If Select is disabled and the user has no server-side signature assigned, no signatures will be displayed in the panel, even if client-side signatures are assigned.
